Abstract

A method and an apparatus for casting concrete products substantially with a horizontal slipforming process, the concrete mass in said method being fed by means of at least one feed element (2) through a limited cross section (13, 7, 8) for forming a concrete product, whereby the feed elements (2, 5, 15, 16) produce a two-directional compacting motion for compacting the concrete mass.

Claims (6)

1. A method for casting concrete products substantially with a horizontal slipforming process, the concrete mass in said method being fed at least by means of one feed element (2) through a limited cross section (13, 7, 8) for forming a concrete product, wherein the feed elements (2, 5, 15, 16) produce a two-directional compacting motion for compacting the concrete mass and the two-directional compacting motion of the feed elements comprises a compacting motion substantially reciprocal with respect to the direction of casting and of a rotational compacting motion in a transversal direction with respect to the direction of casting, characterized in that the compacting motion substantially reciprocal with respect to the direction of casting is provided by means of a feed element consisting of at least a feed screw (2) and a bracket wheel (5, 15, 16) comprising at least one bracket, said bracket wheel being connected fixedly to the end of the feed screw, and the rotational compacting motion in the transversal direction with respect to the direction of casting is provided by means of the bracket wheel (5, 15, 16) of the feed element.
2. An apparatus for casting concrete products substantially with a horizontal slipforming process, the apparatus comprising at least one feed element (2) for feeding the concrete mass through a limited cross section (13, 7, 8) for forming a concrete product, characterized in that the feed element comprises at least one feed screw (2) and a bracket wheel (5, 15, 16) comprising at least one bracket mounted after the feed screw, said bracket wheel being connected fixedly to the end of the feed screw.
3. An apparatus in accordance with Claim 2, characterized in that the bracket wheel (5, 15, 16) advantageously comprises 1 to 10 brackets.
4. An apparatus in accordance with Claim 2 or 3, characterized in that the brackets of the bracket wheel (5, 15, 16) are parallel with the direction of the casting process.
5. An apparatus in accordance with Claim 2 or 3, characterized in that the brackets of the bracket wheel (5, 15, 16) are at an angle of 5 to 30 degrees with respect to the direction of the casting process.
6. A feed element (2) for the apparatus in accordance with Claim 2, characterized in that the feed element comprises a feed screw (2) and a bracket wheel (5, 15, 16) attached to the end of the feed screw in a fixed manner.
